The book is divided into two sections, with the first providing conceptual bases and the second presenting case studies. It describes concepts and applications of transdisciplinary research and participatory action research (PAR). Transdisciplinary research integrates different academic disciplines as well as diverse forms of knowledge, including experiential, cultural, and spiritual. Participatory action research presents a way of engaging all relevant actors in an effort to create an equitable process of research, reflection, and activity to make desired changes. Six case studies show how practitioners have grappled with applying this integration in agroecological work within different geographic and socio-ecological contexts. An explicit and critical discussion of diverse perspectives in the growing field of agroecology, this book covers the conceptual and empirical material of an agroecological approach that aspires to be more transdisciplinary, participatory, and action-oriented. In addition to illustrating systems of agroecology that will improve food systems around the world, it lays the groundwork for further innovations to create better sustainability for all people, ecologies, and landscapes.
